Medical officials reported positive recovery signs for the eleven people wounded in a Michigan Walmart stabbing spree, while questions remain about the suspect.

The man was captured in three minutes thanks to "citizen involvement," Grand Traverse County Sheriff Michael D. Shea said.

Nearly a dozen people were stabbed at a Walmart in Traverse City, Michigan, Saturday afternoon, in what police are calling a “random” act by a lone attacker. Six of the injured were still in critical condition hours later.
